How do I use the Analysis Board?

When analyzing your own games, it's easy to just open the game and click 'analysis.' But what if you want to analyze a made up position, or a game from somewhere else?  With the analysis board, you can analyze any game, opening, or any position at all!

To open the analysis board, hover over 'learn' and then click 'analysis'

This will open the analysis board! And there are several options for how to use it:

From here, you can Load a FEN or PGN of a game you want to analyze. Click here to learn more about PGNs and FENs

Load Previous Analysis will open whatever you were last analyzing, whether it was a game, opening, or a custom position. 

The Details tab will tell you the details of any game you have loaded (the players, the result, etc) and the Openings tab will take you to Openings section of the game explorer. 

The Setup option contains the most use on the analysis board. Let's take a look! 

Setup

Once you click 'setup' you'll get a new menu next to the board: 

You will now be able to drag pieces anywhere you like on the board, or remove them by dragging them off the board to the right. You can set the board up any way you like by adding, moving, or removing pieces. Beware, though, that impossible positions such as multiple kings can cause the computer analysis to be inaccurate or freeze up. 

Below the pieces menu, you have the option to  select whose turn it is in the drop-down, you can also flip the board, or reset the board to starting position, or trash all the pieces and get an empty board

The O-O and O-O-O check-boxes let the computer know if white and black have the right to castle or not. A check in the box means yes, they can castle this way. 

Under the Advanced settings, you can let the computer know if en passant is possible, and on what square. More about en passant here. 

You can also set the Halfmove clock and Fullmove count

The Halfmove clock lets the computer know how many moves have been made toward the 50 move draw. Each halfmove counts as one players move. So if the halfmove clock were set at 99, the next move would be the 50th move toward the 50 move draw (100 half moves), and a draw would be declared.

The Fullmove count is simply a count of how many moves have so far happened in the game. 

Below advanced settings are text boxes for FEN and PGN to be pasted into. After pasting, click Load to load the position. 

Once the board is loaded you'll be able to see the computer's lines, or click on 'run report' to see further analysis!

You can also click 'versus computer' on the very bottom and play the position against the computer!
